Definitions

  • the invention relates to a device for supplying cartridges to a firearm, in particular a multi-tube cannon with a rotating tube bundle, from an ammunition container attached to this weapon according to the preamble of the claim.
  • a transport chain is passed through a feed channel and through a return channel.
  • the feed channel opens into a firearm transfer station.
  • the switch can be switched from its first position to its second position by a switch connected to the weapon.
  • the weapon transfer station continues to rotate until all cartridges have been removed from the second transport chain.
  • the first transport chain continues to move and brings the ammunition into the storage channel.
  • a reversing device then moves the first transport chain backwards until the ammunition out of the Storage channel has returned to the feed channel while the transfer station is completely emptied. This means that the ammunition temporarily contained in the storage channel can be fed to the weapon during the next round of fire.
  • the object to be achieved with the present invention is to provide a device for supplying cartridges to a firearm, with which the empty cartridge cases can be guided away from the firearm, the cartridges being removed from an ammunition container and the empty cartridges being the same ammunition container are fed, the first cartridge being fed to the firearm only after the firing of the gun has ended and further cartridges being fed when the firing burst is stopped when the gun is stopped, but these are no longer fired but are returned to the ammunition container like the empty cartridges. Not only should the first shot of a firing burst be fired after the weapon has started up, but the last shot of the firing burst should also be fired before the weapon is braked.
  • FIG. 1-3 there are three ammunition containers 12, 13 and 14 under a Gatling cannon 10 - with, for example, seven weapon tubes 11 -, of which only the middle ammunition container 13 is visible in FIG.
  • the Gatling cannon 10 is not part of the subject matter of the invention and is therefore not described in more detail here. All that is essential here is that this cannon has a rotating tube bundle 15 which contains the seven weapon tubes 11 mentioned.
  • the first shot should only be fired when the rotating tube bundle 15 rotates at the desired nominal speed.
  • the weapon should not be fired, ie it should be during this time, no cartridge of the weapon 10 can be fed.
  • the cartridge feed should also be accelerated to the required cadence - as will be described further below - without, however, as stated, a cartridge being fed to the weapon.
  • two support arms 17 and 18 are fastened to a base 16, between which the Gatling gun 10 is pivotally mounted about an elevation axis 42.
  • the three ammunition containers 12, 13 and 14 are fastened to the weapon 10 and can be pivoted about the elevation axis 42 with the weapon 10.
  • the transport device 19 with which, as can be seen in FIG. 2, cartridges 20 alternately from the two ammunition containers 12 and 14 on the side middle ammunition container 13 are supplied.
  • the cartridges 20 are removed from the side container 14 at the point 21 and from the other side container 12 at the point 22 and are fed from the transport device 19 to the middle container 13 at the point 23.
  • the transport device 19 has two endless transport chains or conveyor belts 24 and 25, of which one transport chain 24 extends from point 21 to point 23 and from which the other transport chain 25 also extends from point 22 to position 23 extends.
  • the feed chain 29 is therefore flexible and can be rotated in the required manner. For the sake of clarity, however, this twist is not shown in FIG. 8 and the following figures.
  • the feed chain 29 is thus guided at the bottom around a deflection roller 30 and at the top around a deflection roller 31, which are directed at right angles to one another. According to FIG. 1, this rotation takes place in a housing 32.
  • the cartridges 20 are fed in the direction of arrow A on one side of the endless feed chain 29 and the empty sleeves 33 are led away in the direction of arrow A on the other side of the endless feed chain 29.
  • a further endless storage chain 34 which is guided around five deflection wheels 35.
  • the cartridges 20 or the empty sleeves 33 can get from the storage and conveyor chain 26 to the storage chain 34 when the storage and conveyor chain 26 moves in the direction of arrow B.
  • this transfer point 36 there is a switch 37, consisting essentially of two deflection elements 38 and 39. If this switch 37 is in the position according to FIG. 4, the cartridges 20 and the empty sleeves remain on the storage conveyor chain 26 regardless of the direction in which this storage and conveyor chain 26 moves. However, if the switch 37 is in the position according to FIG. 7, the empty sleeves 33 pass from the storage and conveyor chain 26 to the storage chain 34, which is also referred to below as a sleeve loop. However, this is only possible if the storage and conveyor chain 26 moves in the direction of arrow B.
  • the first cartridge 20, which reaches the firearm 10 when firing, is located in the region of a sensing element 40.
  • this first cartridge 20 passes from the storage and conveyor chain 26 onto the Feed chain 29 and to the cannon 10, as shown in Fig.9.
  • both the run-up of the Gatling cannon 10 and the run-up of the feed device have ended, i.e. the storage and conveyor chain 26 and the feed chain 29 move with the cadence required for a series fire.
  • the cartridges 20, which were located in the storage chain 34 (see FIG. 8), entered the storage and conveyor chain 26 during the run-up of the cannon 10 and the feed device (see FIG. 9).
  • the storage chain 34 is thus empty.
  • cartridges 20 are fed to the cannon 10 during a series fire through the endless conveyor chain 29 and empty sleeves 33 are simultaneously fed to the storage and conveyor chain 26. 10 also shows that no cartridge 20 or empty sleeves 33 get onto the storage chain 34 during a series fire.
  • the Switch 37 is in the position according to Fig. 4 during a series fire.
  • the cannon 10 When a burst of fire ends, the cannon 10 does not stop immediately, but continues to run due to its great inertia, so that, as can be seen from FIG 11, the first cartridge 20 is located in the area of the switch 37 and likewise the empty sleeve 33 of the cartridge 20 that was last fired is located in the area of this switch 37.
  • the cartridges 20 have to be transported back again.
  • the storage and conveyor chain 26, the feed chain 29 and also the storage chain 34 move in the opposite direction, as indicated by the arrows B.
  • the switch 37 has been switched.
  • the empty sleeves 33 now arrive on the storage chain 34, which is why this chain 34 is also referred to as a sleeve loop.
  • the cartridges 20 now pass from the switch 37 to the weapon 10 without being fired there.
  • this return has ended when the first cartridge 20 is again in the region of the sensing element 40.
  • the empty sleeves 33 have filled the greater part of the storage chain 34 during this return. Without this sleeve loop, the described return would not be possible, since otherwise empty sleeves 33 would have had to be fed to the firearm 10, which is not very useful since the cannon would experience an additional unnecessary load when the sleeves were fed again and sleeves were in after each burst of fire the cannon, which would have to be removed for any maintenance, which means an additional expenditure of time. With the Sleeve loop 34 can avoid these additional loads on the cannon.
  • the first shot of the second burst of fire is not fired until the first cartridge 20 has in turn reached from the sensing element 40 to the cannon 10.
  • the storage chain or sleeve loop 34 has partially emptied again from the sleeves 33.
  • the last sleeve 33 of the first burst of fire arrives from the sleeve loop 34 directly next to the first sleeve 33 of the second burst of fire in the storage and conveyor chain 26 of the cartridge magazine.
  • the switch 37 consists of a pivotable deflection element 38 and a displaceable deflection element 39. Furthermore, a conveying star 41 is arranged at the transfer point 36, which rotates counterclockwise when the cartridges 20 in the direction of arrow A of the firearm 10 are supplied and which rotates clockwise when the cartridges 20 are transported back in the direction of arrow B.
  • the cartridge feeder Before the first shot of a burst of fire is fired with the weapon 10, the cartridges 20 are in the starting position according to FIGS. 8 and 1. As soon as the trigger of the firearm 10 is actuated, the storage and conveyor chain 26 begins to move in the direction of the arrows A (FIGS. 1 and 8). At the same time, the feed chain 29 and the storage chain 34 also move in the direction of the arrows A. This movement on the one hand brings the first cartridge 20 to the weapon 10 and, on the other hand, cartridges 20 are transported from the storage chain 34 into the storage and conveyor chain 26, as shown in FIG .9 can be seen. As soon as the first cartridge 20 has reached the weapon 10, the first shot can be fired.
